Obsession, a novel by Ted Dekker (author of "Christian novels" with Gothic covers):
Dekker's not just writing fiction here. He has a point--that man is made to obsess, ultimately to obsess for God as God obsesses for man. He also says that we are willing to pay (in money, time, effort, whatever) for what we value; that the reason what we value has value is what we would be willing to sacrifice for it. He makes his point almost to belaboring it. Too many different characters coincidentally saying the same thing.

I think overall he pulls it off. He makes his point.

I just wish I could find some "Christian fiction" that doesn't include conspiracies, ancient relics, or secret powers. This one kind of hit two out of three. Read it to find out which ones!

Oh well.
